STOCK-OILER.

Specification of Letters Patent.

Patented May 23, 1916..

Application led November 15, 1915. Serial No. 61,604.

To all wwm t may concern Be it known that we, LLOYD E. GAMBLE and VILLIAM THAoxnnAY, citizens of the United States, residing at Kewanee, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Stock-Oilers, of which the following is a Specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in stock oilers; .and it is an obj ect of the invention to provide a device of this general character having novel and improved means whereby the discharge of the oil is under control of the stock.

Furthermore, it is an object of the invention to provide a device of this general character including an applying member adapted to engage the animal to be oiled and whereby the flow of the oil is under control of the movement imparted to the applying member by the contact of the animal therewith.

It is also an object of the invention to provide a device of this general character having novel and improved means whereby a predetermined quantity of oil is delivered at each operation of the device.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved stock oiler whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient .and advantageous for use, all as will be hereinafter more fully set forth. y

The novel features of the invention will be carefully defined in the appended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a view in elevation with parts broken away of an oiler constructed in accordance with an embodiment of our invention; Fig. 2 is an enlarged sectional view taken substantially on the line 2-2 of Fig. l; Fig. 3 is a fragmentary view in perspective, illustrating acertain feature'of the invention as herein included; .and Fig. 4 is a view in perspective detached of one of the supporting members.

As disclosed in the accompanying drawings, F denotes a frame substantially in the form of an inverted U and having adjustably engaged with the vertical posts 1 thereof the supporting shaft 2. The adjustment of the shaft is yafforded in order to compensate for the various sizes of stock, such as hogs, sheep or cattle, with which the device 1s adapted to be used and it is thought to be self-evident that the animal to be oiled passes through the frame F. The shaft 2 is capable of axial rotation .and has depending therefrom the applying members 3, herein disclosed as in the form of conventional broom heads and discharging upon the butts of said applying members are the discharge branches 4E of the discharge pipes 5 leading from the lower end of the tube G suitably se? cured to `an outer face of the tank or reservoir 7 also operatively supported by the shaft 2. The tube 6 is divided intermediate its length by the partition 8 into two compartments a and b, the lower compartment a lbeing of aA predetermined capacity and controlling the amount of oil discharged upon the applying members 3. The upper compartment b is in communication with the reservoir or tank 7, as indicated at 9, and the partition 8 is provided with an opening l() affording communication between the compartments a and b.

Communication between the discharge pipe 5 and the lower end of the tube G is normally closed by the valve l1 carried by the stem 12 extending longitudinally of the tube 6 and the valve is maintained in such position through the iniuenee of the spring 14. The stem 12 is Valso provided with a valve 15 adapted to close the opening l0 when the valve 1l israised so that ingress of oil within the lower compartment a is prevented when said lower compartment is emptying.

The upper extremity of the stem 12 has secured thereto the iexible members 16 secured to the opposite ends of the cross bar 17 carried by the upper beam 18 of the frame F whereby it will be perceived that upon an animal passing under the members or brooms 3, the resultant rotation of the shaft 2 will cause the stem 12 to be elevated and the valves 11 and 15 to be adjusted, respectively, into open and closed positions. It will therefore be appreciated that the oil within the lower compartment will only be discharged when an animal passes under the applying members 3.4 It will also be self-evident that should the animal stand beneath the brushes and maintain the same slightly elevated that the oil which will be discharged will be only the oil contained within ythe lower compartment a. It is also to be understood that we have in communication with the lower compartment a through the partition 8 the vent'l) leading from the atmosphere so that the liow of the oil within the lower compartment a, when the valve 1l is in open adjustment, will be discharged. Y

le find it of advantage to incase the upper portion of the applying members 3 within a metallic sheathing 20 secured to the applying members 3 in any desired manner. Ve have also found it desirable to secure to the inner faces of the posts 1 the U-shaped stop members 21 as particularly illustrated in Fig. 4f which serve to limit therocking movement of the applying members.

From the foregoing description, it is thought t0 be obvious that a stock oiler vconstructed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that our invention susceptible. of some change and modification without material departure from the principles and spirit thereof and for this reasonwe do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several yparts herein shown in carrying out our invention in practice.

lVe claim:

1. A device of the character described comprising a shaft mounted for rocking movement, an applying member depending therefrom, a reservoir carried by the shaft, a delivery pipe leading from the reservoir to the applying member, a valve for controlling the flow through said pipe, and

and discharging upon the applying mem,

ber, means under control of the movement of the shaft for controlling the discharge from the reservoir, and means coactring with the applying member for limiting the rocking movement of the shaft.

il. A device of the character described` comprising an applying member mounted for rocking movement, a tube discharging upon the applying member, a source of'supply in communication with the tube, a valve within the tube for controlling the discharge therefrom, a stem carried by the valve and extending exteriorly of the tube, lav fixedV bar positioned above the axis of the rocking member and extending at opposite sides of the applying member and in the same general direction as the movement of said rockingV member, and connections between the outer portionof the stem of the valvea-nd opposite end portions of the fixed. bar, whereby said valve is adjusted into an open position upon rocking movement of the applying member in either direction.

In testimony whereof we hereunto affix our signatures. i
